PH of a solution which contain CO is less than 7.
Explanation:
- Carbon monoxide(CO) is a non metallic oxide as carbon is a non-metal.
- Metallic and non metallic oxides differ in terms of their acidic or basic nature.
- Metallic oxides are usually basic in nature whereas on metallic oxides have acidic nature.
- Carbon monoxide CO has a slight acidic nature. Hence its PH value will be less than 7.
- In the PH scale,7 corresponds to neutral nature while values less than 7 indicate acidic nature and values greater than 7 indicate basic nature.
